The PulseRider is a novel endovascular device specifically designed to treat bifurcation intracranial aneurysms with wide necks. In an international series, we report the results of PulseRider stent-assisted coiling of 15 patients (9 women and 6 men; mean age, 62.6 years) with 15 unruptured wide-neck (median dome size, 8 mm; median neck size, 5 mm) bifurcation aneurysms. Failure of PulseRider treatment occurred in 1 case, and 1 intraprocedural thromboembolic complication was observed. There was no mortality or neurologic permanent morbidity at discharge and at 1 month. Immediate angiographic outcome showed 12 complete occlusions and 2 neck remnants. Follow-up at 6 months was available for 3 aneurysms and demonstrated 2 complete aneurysm occlusions and 1 growing neck remnant. In this small series of selected patients, PulseRider stent-assisted coiling of wide-neck bifurcation aneurysms was feasible with low procedural complication rates. Angiographic follow-up will be required to evaluate the efficacy of the PulseRider device.
脉冲支架（PulseRider）是一种专门设计用于治疗宽颈分叉颅内动脉瘤的新型血管内装置。在一项国际研究中，我们报告了15例（9例女性和6例男性；平均年龄62.6岁）未破裂宽颈（瘤顶大小中位数为8mm；瘤颈大小中位数为5mm）分叉动脉瘤患者采用脉冲支架辅助弹簧圈栓塞治疗的结果。脉冲支架治疗失败1例，观察到1例术中血栓栓塞并发症。出院时及1个月时无死亡或永久性神经功能缺损。即刻血管造影结果显示12例完全闭塞，2例瘤颈残留。3个动脉瘤有6个月的随访，显示2例动脉瘤完全闭塞，1例瘤颈残留增大。在这一小系列特定患者中，脉冲支架辅助弹簧圈栓塞宽颈分叉动脉瘤是可行的，手术并发症发生率低。需要进行血管造影随访以评估脉冲支架装置的疗效。
